I don't understand your criticism of Quinnipiac in Colorado:
Quinnipiac only polled CO in 2008 and 2012 and in 2008 they had one of the best final CO polls out there, showing Obama winning by 9 (he won by 9).

In 2012, Quinnipiac conducted their CO poll right after Obama's disaster of first debate and of course Romney was up by 1 in this one. Too bad they didn't release a final poll closer to the election.
But in general, Quinnipiac is a solid pollster and they had good results in 2012.

There's another simple explanation for CO and Hillary: She suxx in this state (but that can change during the actual 2016 campaign between summer and election day).
Colorado is rare in the fact that Rs outnumber Ds but liberals have a smaller deficit to conservatives compared to national numbers. Basically, the roles between Democrats (the party with the most registered but less organized) and Republicans are reversed.
